Function Blocks for Acyclic Data Exchange CM574-RS/AC500 \ CPUΒΆ
Unlike the cyclic data exchange via input/output signals, the acyclic data exchange has to be programmed in the user program.
The acyclic data exchange is used mainly for transmitting commands for own protocols. For example, the entire data exchange between the AC500 CPU and a CM574-RCOM occurs via these blocks.
The following blocks are available:
| Description | CM574-RS | AC500 CPU |
|---|---|---|
| Library | SysIntExt_AC500_V13.lib | SysInt_AC500_V10.lib |
| Transmission from the CM574 to the AC500 CPU or reception in the AC500 CPU from the Communication Module | DPRAM_PM5XX_SEND: DPRAM_PM5XX_SEND DPRAM_PM5XX_SEND | DPRAM_CM5XX_SEND: DPRAM_CM5XX_SEND DPRAM_CM5XX_SEND |
| Reception in the CM574 from the AC500 CPU or transmission from the AC500 CPU to the Communication Module | DPRAM_PM5XX_REC: DPRAM_PM5XX_REC DPRAM_PM5XX_REC | DPRAM_CM5XX_REC: DPRAM_CM5XX_REC DPRAM_CM5XX_REC |
